I made a "fast and ugly" idler wheel on the chains bottom-run from a bolt with two wide washers as side-plates, and several plastic washers as the roller. I will likely buy a more professional-looking idler sometime later.
I wanted the bike to roll easily when folded up, and the rear tire was rubbing up against the BB. Also, when loading/unloading from my truck or bringing it indoors, the rear flopped around. So, I made a fold-up pin-latch out of organic composite fiber (wood).
I dug through my pile of bike parts, and the kick-stand I liked most was tubular aluminum from a 24" bike (too short). So I cut it in half, bought a $5 tap to cut ID threads and added a section of all-thread-rod and two locknuts.
All the mechanics at Big Poppi bikes were very helpful and encouraging. They sold me derailleur cable housing at $1/foot (any length) and threw in some aluminum housing-tips for free so I could experiment. They would have crimped two cables together for free, but I ordered a 10-ft continuous cable from a recumbent site (coiled up in picture at the derailleur). So now I have 6 gears on the rear, and I didn't really need the front derailleur for the BB as its pretty flat terrain here.
I really like having my feet flat on the ground at stops. There's a lot of potholes and rough sidewalk in Junction City so the fat tires and full-suspension are well worth the effort for me. The red seat tube is from a trash-day steel BMX, and soon both the seat tube and shock mount will be completely changed into something that looks more professional. I'm envisioning a four-legged spider for both seat/shock that frees up the space under the seat between the stays, with the shock being horizontal.
The left/right edges of the flat aluminum shock mounting plate occasionally brush against my ankles when pedaling, so if I was in a hurry to do this again, I would use an aluminum squared C-channel section attached between the seat stays, with the four U-clamps coming in from the sides. The most pressing need right now is a cup-holder and music.
Ft Riley, Kansas was home to George "I aint afraid of no Indians" Custer, and Patton. The stone pillar in the pic is one of the many 130-year old hitching posts here. Originally for horses, they are now used for decoration.
